Inserting Library Processes into a Workflow - trillium_discovery - trillium_quality - 17.2

If you plan to insert library processes into the middle of an existing Quality process workflow (instead of connecting to the initial data input), you must make a disconnection in the target flow, add the new flow or process, and reconnect the new flow or process back to the existing workflow.

1. Copy the library project that contains the Transformer process into the existing Quality project.

   See example:

   

2. Add new input to the Transformer process by dragging its output onto the output of the Relationship Linker process.

   See example:

   

3. Map attributes in the Schema Editor of the Transformer, as needed.
4. Change the Commonizer's default schema from an inherited schema to an editable schema:
   1. Open the Commonizer process for editing.
   2. In the Schema Editor, click Regenerate Output Schema.
   3. Select Edit Schema.
   4. Click Apply.
   5. Click Finish.

   All processes use an inherited schema by default. Modifying the schema to be editable allows you to map the attributes from the Transformer onto the Commonizer output attributes.

   See example:

   

   Note: Ensure you enable the Commonizer's schema for editing before you disconnect the Commonizer from the Relationship Linker process (Step 5) or the Transformer output attributes cannot be mapped and the process cannot be properly connected to the existing flow.
5. Remove the connection between the Relationship Linker and the Commonizer by right-clicking the arrow from of the Relationship Linker output and selecting Remove this input. This leaves the Commonizer disconnected.

   See example:

   

6. Add new input to the Commonizer by dragging its output onto the output of the Transformer.

   See example:

   

7. Connect the Transformer to the Commonizer by mapping the attributes in the Schema Editor of the Commonizer, as needed.
8. Run the project to generate the new output data.
